It's very simple for ordinary people to make money in this market; just buy the big pie. Buy in at the bottom of a bear market, ride out a big cycle, and you don't need to master 18 different skills, just learning one or two tricks is enough. If you really want to make big money, it depends on fate and luck. For example, if you buy at the bottom and get 10-20 times returns, then you have increased your capital. In the next round, just doing it again to get 3-5 times is enough. Actually, all financial markets can be approached this way!
